Installing the appropriate combo update may help...
If you are running v10..7 Lion, install the OS X Lion Update 10.7.4 (Client Combo)
For 10.6 Snow Leopard > Mac OS X 10.6.8 Update Combo
Then restart your Mac. Try the App Store.
If that doesn't help, try the following..
Quit the App Store if it's open.
Open the Finder. From the Finder menu bar top of your screen click Go > Go to Folder
Type this exactly as you see it here:
/Library/Preferences/SystemConfiguration
Click Go
Move the NetworkInterfaces.plist file from the SystemConfiguration folder to the Trash.
Relaunch the App Store and try downloading Mountain Lion.
You may also need to disable anti virus software and turn off the Firewall in System Preferences > Security (or Security & Privacy) > Firewall

Problem installing Mountain Lion on Mac Pro 3 - currently Snow Leopard

Look at the hard drive where Applications, Library, System, and Users are. There is most likely a backup file there. Delete it.

Can someone help me install itunes? i keep getting an error message

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.
Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?
If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? (For example, 8007000B.)

I just tried to buy Mountain Lion but I am getting this message, yes, even after I reboot: The product distribution file could not be verified. It may be damaged or was not signed.
I don't understand what this means? Is my MacBookPro too old to work with Mountain Lion?

I tried to download the latest OSX Mountain Lion and got this notice - "We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed. " What does this mean and why can't I download it?

I tried to download the latest OSX for my iMac - Mountain Lion.
This is the message that I received:
"We could not complete your purchase. The product distribution file could not be verified. It may be damaged or was not signed."
What does this mean?

The only thing that worked for me was to boot in safe mode.
Power down. Then press power button and hold 'shift' key until grey screen with progress bar appears... Once booted and logged in just open safari and browse to applestore.
No trouble at all once I did this.
Reminder: create full backup before you upgrade OS
Hope it helps.

Hi, every time I attempt to purchase OXS Mountain Lion I get a message that says unable to complete your purchase because "The product distribution file could not be verified. It may be damaged or was not signed." Any idea what I am doing wrong, cheers.

I've tried to purchase Mountain Lion but when I click 'buy' I get the message, "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer." I'm using an iMac with Lion OS on it, Why is it incompatible?

Your Mac must be one of the following models:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Xserve (Early 2009)

Absolutely. A proxy can prevent the software from downloading and installing.
I realize you have already purchased Lion from the App Store but a workaround in your case would be the thumb drive.
OS X Lion USB Thumb Drive - Apple Store

Welcome to the Apple Support Communities
Mountain Lion is a 64-bit operating system, and an Intel Core Duo processor is only 32-bit, so you can't use Mountain Lion on your Mac. You can keep using your actual OS X version or buy a new Mac if you want Mountain Lion
